It is indeed a good and praiseworthy thing to progress materially, but in so doing, let us not neglect the more important spiritual progress, and close our eyes to the Divine light shining in our midst.

Only by improving spiritually as well as materially can we make any real progress, and become perfect beings. It was in order to bring this spiritual life and light into the world that all the great Teachers have appeared. They came so that the Sun of Truth might be manifested, and shine in the hearts of men, and that through its wondrous power men might attain unto Everlasting Light. 
- ‘Abdu’l-Baha  (From a talk, November 2, 1911, ‘Paris Talks’)
